Abstract
Department of Chemistry, Institute of Science, Bombay-400 032 <em>Manuscript received 5 April 1982, revised 9 November 1982, accepted 19 March 1983</em> Dioxouranium(VI) complexes of some Schiff bases, obtained by condensing chloroanilines and toluidines with salicylaldehyde are synthesised and characterised by elemental analysis, spectral and conductance data. All the complexes are orange red in colour, microcrystalline in nature and form compounds of the type [UO<sub>2</sub>(LH)<sub>2</sub>](NO<sub>3</sub>)<sub>2</sub> where LH is a Schiff base molecule. The bonding with the metal in the complexes takes place from hydroxyl oxygen and imine nitrogen of the ligand. It is observed that dioxouranium(VI) forms 1 : 2 adducts with these Schiff bases. Conductivity measurements, analytical data and spectral study show that these complexes have coordination number eight with hexagonal bipyramid structure.
